MIL-PRF-81322 is a US military specification for lubricating oils, intended for use in aircraft turbine engines.

There are two variations of this spec. The variations are as follows -

  1. MIL-PRF-81322 (formerly MIL-L-81322) Type I: This type is intended for general-purpose use in aircraft turbine engines. It is a synthetic-based oil with additives to enhance its performance and protect against wear and corrosion.

  2. MIL-PRF-81322 (formerly MIL-L-81322) Type II: This type is a low-temperature variant designed to provide lubrication in extreme cold conditions. It also contains synthetic base oils and additives for improved low-temperature properties.

These lubricating oils are developed to meet the specific needs of military aircraft turbine engines, providing effective lubrication under a range of operating conditions. It's crucial to consult the latest version of the MIL-PRF-81322 specification for the most accurate and up-to-date information.
